The 40 Meter Series 30 Meter (40mS30m) is an amateur radio band that lies just below the 40 meter band and just above the 30 meter band. It is a continuation of the 40 meter band, and is defined in part by the same international treaty that defines the 40 meter band.
The 40 Meter Series 30 Meter band has been allocated to the Amateur Service by the International Telecommunications Union (ITU) in Region 2, and is also available in many other parts of the world.
The 40 Meter Series 30 Meter band is a center-fed half-wave dipole antenna that is about 28.5 feet (8.7 meters) long. It is resonant at about 10.15 MHz, and can be used to transmit and receive voice and CW signals.
The 40 Meter Series 30 Meter band is a good choice for a first HF band, because the antennas are relatively short and easy to build, and the operating frequencies are near the middle of the HF spectrum, where there is less noise and interference than at the lower or higher frequencies.
Conclusion
Series creator Takahashi has hinted that there could be more to come from the 40M series. Judging by the popularity of the 40M games thus far, it seems likely that more episodes will be released in the future. Fans of the 40M series can only hope that Takahashi will continue to produce more exciting and innovative games in the future.
